简要总结
This study is aimed to evaluate and compare the efficacy of cordlessretraction systems (retraction pastes) and conventional retraction cords inachieving gingival displacement and their impact on the accuracy ofintraoral digital impressions for fixed prostheses.The studyis to be conducted with 30 sample and are divided into 2groups were subjected to single crownpreferably. Clinical parameter such as gingival sulcus width is measured atbaseline and post retraction. The impressionsare made using intra oral scanning ( DENTSPLY PRIMESCAN ).The accuracy of thefit of the crown is analysed with the help of the stereomicroscope ( Magnus MSZ-TR RELEV)
